Beacon-Based Door Access Authentication Using Movement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access management systems face inefficiencies in user authentication, particularly when multiple users need to access a door, as they require separate authentication devices and can be inconvenient, with risks of lost or stolen authentication means allowing unauthorized access.
Innovation Solution
A method and system using beacon signals to determine user movement and authenticate access, where beacons are installed on both sides of a door, allowing users to carry a terminal that receives beacon data to identify the door and determine entry or exit movements, thereby simplifying authentication processes and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods using magnetic cards or biometric devices are used, then security can be maintained, but user convenience deteriorates and authentication time increases
Solution Approach 1:
The patent replaces mechanical authentication devices (magnetic card readers, fingerprint scanners) with a beacon-based wireless authentication system. Beacons transmit authentication data wirelessly to terminals, eliminating the need for physical interaction with authentication devices while maintaining security through encrypted beacon data transmission.
Solution Approach 2:
The patent introduces beacons as intermediary devices that mediate between the authentication system and users. Beacons carry authentication data and transmit it to terminals, serving as a mobile authentication medium that eliminates the need for separate authentication devices while maintaining security through encrypted data transmission.
2Reliability
If multiple visitors need to authenticate simultaneously using conventional methods, then security is maintained, but authentication time increases significantly
Solution Approach 1:
The patent replaces sequential mechanical authentication processes with parallel wireless beacon-based authentication. Multiple terminals can simultaneously receive and process beacon data without interfering with each other, enabling concurrent authentication of multiple users while maintaining security through individual encrypted sessions.
Solution Approach 2:
The patent performs preliminary authentication by having terminals continuously receive and process beacon data in advance. When a user approaches the door, authentication is already prepared through continuous beacon monitoring, eliminating the need for manual authentication actions at the moment of door access.
3Reliability
If separate authentication devices are required for each user, then security is maintained, but device complexity and loss risk increase
Solution Approach 1:
The patent makes terminals universal authentication devices that can function as both the authentication medium and the authentication receiver. The same terminal device serves multiple purposes: storing user information, receiving beacon data, and processing authentication, eliminating the need for separate dedicated authentication devices for each user.
Solution Approach 2:
The patent merges the authentication medium (beacon data), the authentication processor (terminal), and the authentication verifier (access control system) into an integrated wireless authentication system. This consolidation eliminates separate authentication devices while maintaining security through encrypted beacon data transmission and centralized access control.
4Reliability
If authentication requires manual interaction with authentication devices, then security verification is ensured, but user convenience and speed deteriorate
Solution Approach 1:
The patent performs preliminary authentication by having terminals continuously receive and verify beacon data in advance of door access. Users don't need to manually initiate authentication when reaching the door, as the system has already verified their credentials through continuous beacon monitoring, enabling seamless passage while maintaining security verification.
Solution Approach 2:
The patent replaces manual authentication interactions (inserting cards, pressing fingers) with automated wireless beacon data reception and processing. Terminals automatically receive, decrypt, and verify beacon data without user intervention, eliminating mechanical authentication actions while maintaining authentication accuracy through encrypted data verification.

AI summary
A method and system allow management of access to a door using a beacon signal. A user access authority determination unit controls access of a user to a target door based beacon data from beacons installed near a door. The user carries a terminal that obtains the beacon data based on a proximity to the beacons. The method includes identifying the target door based on identification information of the beacons extracted from the beacon data. A type of user movement is determined. The type of user movement includes an entering movement that the user enters into an inner side from an outer side through the target door and an exiting movement that the user exits the inner side to the outer side through the target door. An access authentication process to be performed to unlock the target door is determined according to the determined type of user movement.
